WTF... Dude... Idk what kind of mental gymnastics the marketing team of that "kagi" service had to make in order to actually convince you, it's only single user to pay for it, but if you have to login to use a web search then it offers less privacy than whatever alternative, even google.
I was reading though their FAQ and they actually try to rationalize that lack of results isn't a bug it's a feature...
Besides, there's no point in posting a link for it here, since no-one here will be able to open it.
